Post-training is starting to look like maintenance work, not magic
A useful AI research signal this week is the move to describe LLM post-training as industrial maintenance. That framing is important because many model improvements depend less on mystery and more on cleaning, shaping, measuring, and repairing the data systems around the model.
Why it matters: For builders, this makes model quality a process question. The teams that improve fastest will likely be the ones with the best feedback loops, data hygiene, and evaluation discipline, not only the biggest base model.
